@Carmella7 Yes, it's painful to lose that kind of money, but unfortunately I don't think you'll have any luck trying to retreive it. These scammers can't really be tracked down, it seems.
Life is a constant learning experience, and this was an expensive lesson to research how something really works (like going to the official Airbnb site and reading up about how bookings and payments are made before falling for lies about it), and never sending money to strangers you met online.
Something similar happened to my daughter when she was 19, but it wasn't an online scam. She and her friend had bought tickets for flights to Nepal from a travel agent. The tickets were supposed to be mailed, but never arrived and when she phoned the agency, the phone was never answered and messages not returned. It turned out the agency had gone out of business. But because it was a real business with an office, the police tracked down the registered owners and they were made to send the tickets, which in fact they had, but had just kept and perhaps were going to try to cash in.
